	* Branchpoint for 5.0 (cvs tag -b branch-5-0-stable)

	The main (development) branch is now marked 5.1 and will eventually
	be used as the basis for a future release named gnuplot version 5.2.

				>>> NOTE <<<

	Starting now
	============

	* Bugfixes for version 5 should be applied to both the main branch
	(5.1 == this one) and the stable branch (branch-5-0-stable).
	They will first appear in patchlevel releases 5.0.1, 5.0.2, and so on.

	* Major new features and experimental changes belong here, not in the
	stable branch.  They will appear eventually in release 5.2.

	* Minor new features can go in both branches at your discretion, but
	remember that the stable branch should ideally never break.
	That means new code should be tested here in the development
	branch first, and only after testing be added or back-ported to the
	stable branch.

2014-08-20  Ethan A Merritt  <merritt@u.washington.edu>

	* src/wxterminal/gp_cairo.c:  Distinct empirical scale factors for
	dashlength used by pngcairo, pdfcairo, and wxt.
	* term/emf.trm:  Scale dashlength with current linewidth.

2014-08-18  Ethan A Merritt  <merritt@u.washington.edu>

	* src/graphics.c (place_arrows) src/graph3d.c (place_arrows3d):
	Only invoke the arrowheads only code if there really is an arrowhead.

2014-08-18  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* config/mingw/Makefile (VPATH): Drop $W from VPATH.  Necessary to
	avoid circular dependency on wgnuplot.mnu
	(%.$(O)): Use pattern rule instead of VPATH to build Windows
	source files.
	(VERSIONING): Avoid inverted logic in makefile conditional.
	(console, windows, pipes): Simplify by letting the default rule in
	the sub-make handle things.
	(default, all): Versioning is really needed by $(TARGET) rule,
	so let that handle constructing it.
	($(TARGET)): Do VERSIONING first, drop dependencies on icon files.
	(%.o): Use pattern rules to build Qt source files.  Much simpler
	than spelling it out long hand for every single source file.

2014-08-15  Ethan A Merritt  <merritt@u.washington.edu>

	* src/bf_test.c src/Makefile.am src/binary.* (removed)
	config/makefile.os2 config/makefile.dj2 config/makefile.cyg
	config/cygwin/Makefile config/mingw/Makefile config/msvc/Makefile:
	Remove bf_test dependence on all other gnuplot files and libraries.
	This makes binary.c and binary.h superfluous.
	Bugs #1412 #1451

	* src/makefile.all src/makefile.awc: Remove mention of binary.o

	* config/*/Makefile: Remove alloc and binary from bf_test dependencies

	* src/graphics.c (place_objects) src/set.c (set_obj):
	Apply default rectangle style at the time of a "set object rect"
	command rather than waiting until the rectangle is drawn.  This prevents
	the default style line/dash settings from overriding explicit rectangle
	commands.
	Bug #1460

	* src/save.c (save_linetype):  Bugfix - dashtype was being saved only if
	there was also a point type.

	* src/gadgets.c (apply_pm3dcolor):  Don't clobber current dashtype by
	calling term->linetype(LT_BLACK).  Call term->set_color(BLACK_COLORSPEC)
	instead.

	* src/graphics.c (place_arrows) src/graph3d.c (place_arrows3d):
	Force solid lines for arrow heads.

2014-08-15  Shigeharu Takeno  <shige@iee.niit.ac.jp>

	* src/gplt_x11.c:  For single byte fonts gnuplot_x11 uses a list of
	previously used fonts to speed up the search for a new target font.
	Now we add an equivalent for multi-byte font search.

2014-08-14  Ethan A Merritt  <merritt@u.washington.edu>

	* src/graphics.c (do_rectangle) src/graph3d.c (map3d_position_r)
	demo/rectangle.dem:  Fix y extent and clipping of rectangles with
	negative y coord or inverted axes.
	Bug #1462

2014-08-05  Ethan A Merritt  <merritt@u.washington.edu>

	* src/mouse.c (event_buttonpress):  Remove extraneous event_reset.

2014-08-02  Ethan A Merritt  <merritt@u.washington.edu>

	* src/misc.c (parse_colorspec):  Apply user-defined line colors
	to text color also.
	Bug #1452

	src/misc.c src/save.c src/set.c src/term.c src/term_api.h:
	Store custom dashtype string as a constant length character array
	rather than a dynamically allocated string.  This fixes memory
	leakage that happened whenever a linetype using dashes was discarded.

2014-08-01  Ethan A Merritt  <merritt@u.washington.edu>

	* src/mouse.c (event_buttonpress):  Trap mouse button click on
	press rather than on release so that "pause mouse {button1|any}"
	takes precedence over a key binding to the mouse button.
	Bugfix

2014-07-30  Ethan A Merritt  <merritt@u.washington.edu>

	* term/x11.trm:  Remove misleading mention of -noevents.  This is a
	command line option for gnuplot_x11, not for gnuplot itself.

	* src/datafile.c docs/gnuplot.doc demo/heatmaps.dem:
	New text input matrix keywords `columnheaders` and `rowheaders`.
	These handle reading matrix data from a csv file in which the first
	row and/or column contains labels rather than data.

	* src/eval.c (update_plot_bounds):  Provide a user-visible copy of
	the current terminal scale (oversampling, etc) as GPVAL_TERM_SCALE.
	Bug #1291

2014-07-28  Allin Cottrell  <cottrell@wfu.edu>

	* src/syscfg.h:  Report 32/64 bit Windows build in version string

2014-07-28  Ethan A Merritt  <merritt@u.washington.edu>

	* src/wxterminal/gp_cairo.c:  Do not pass a linewidth of zero to the
	cairo library.  The linewidth of LT_AXIS is now set in the core code,
	do not further reduce it in gp_cairo_stroke().

2014-07-25  Ethan A Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c: Scale x11 dashlength with linewidth.

2014-07-23  Shigeharu Takeno  <shige@iee.niit.ac.jp>

	* src/mouse.c src/mouse.h src/set.c src/show.c docs/gnuplot.doc:
	New command 'set mouse zoomfactors <xfactor>,<yfactor>'

2014-07-22  Ethan A Merritt  <merritt@u.washington.edu>

	* src/gp_types.h src/plot2d.c (store2d_point):
	INRANGE/OUTRANGE refer to points that are inside/outside the plot
	boundaries as defined by xrange, yrange, etc.  They fail to handle
	points that are outside theta range limits given for polar data.
	That is, a point may be outside of trange [pi/2:pi] even though it
	would lie well inside the plot boundaries if drawn.
	Add a new category EXCLUDEDRANGE for such points.

	* src/graphics.c (plot_impulses):  Test for EXCLUDEDRANGE data points
	so that set trange [theta_min:theta_max] actually does something.
	Bug #1439

	* demo/poldat.dem:  Make sure trange includes the whole plot.

2014-07-18  Ethan A Merritt  <merritt@u.washington.edu>

	* demo/Makefile.am.in: Do not create a symlink to GNUPLOT_X11 in the
	build directory during "make check". This was probably intended to
	handle the rare case of ./configure --program-suffix=foo but it breaks
	the more common case of configuring on a system without x11 support
	and then running "make check" twice.
	Bugfix

2014-07-14  Ethan A Merritt  <merritt@u.washington.edu>

	* src/gadgets.c src/save.c src/set.c src/gadgets.h:
	Continue to recognize "set style increment user" even though it has
	been deprecated in favor of "set linetype".
	Bug #1411 (not really a bug)

2014-07-12  Ethan A Merritt  <merritt@u.washington.edu>

	* src/parse.c (check_for_iteration):  Fix failure to detect some loop
	[start:end:increment] combinations that should be executed only once
	or not executed at all.
	Bug #1441

2014-07-10  Ethan A Merritt  <merritt@u.washington.edu>

	* src/set.c (set_dummy):  More sanity checks on "set dummy" syntax.
	Bug #1442

2014-07-06  Ethan A Merritt  <merritt@u.washington.edu>

	* src/set.c (load_tic_user):  "set Xtics ()" should clear the list
	of user-specified tics rather than setting tic generation to auto.

2014-07-04  Shigeharu Takeno  <shige@iee.niit.ac.jp>

	* docs/gnuplot.doc docs/term-ja.diff docs/gnuplot-ja.doc
	man/gnuplot.1 man/gnuplot-ja.1:
	Fix typos. Sync Japanese documentation to 1.896

2014-07-04  Bastian Maerkisch  <bmaerkisch@web.de>

	* src/win/wgraph.c:  'q' closes graph window.

	* src/qtterminal/qt_term.cpp (qt_options) term/wxt.trm (wxt_options):
	On Windows, the wxt and qt terminals can be used in the same session.

2014-07-01  Ethan A Merritt  <merritt@u.washington.edu>

	* term/cairo.trm, term/wxt.trm:
	Always report {no}enhanced property in "show term".

	* src/color.c: If the current terminal has property "monochrome" then
	convert all requests for constant color as "black".
	Bug #1423

2014-06-24  Ethan A Merritt  <merritt@u.washington.edu>

	* src/set.c src/show.c src/tables.c docs/gnuplot.doc:
	New command:  set margins <left>, <right>, <top>, <bottom>
	acts just like four successive commands set lmargin <left>, ...

	* src/unset.c:  unset margins

2014-06-20  Ethan A Merritt  <merritt@u.washington.edu>

	* configure.in src/wxterminal/wxt_gui.h:  The configuration test for
	wxWidgets >= 2.8 had no effect on code generation. Remove this test.

	* configure.in src/wxterminal/wxt_gui.h:  Revert the attemp to guess
	whether -lX11 is required by wxt. As feared, this causes problems on OSX
	and other platforms where wx is built on top of something other than X11.

2014-06-16  Karl Ratzsch  <ratzsch@uni-freiburg.de>

	* fit.c:  FIT_NITER holds number of iterations used by previous fit.

2014-06-16  Ethan A Merritt  <merritt@u.washington.edu>

	* configure.in src/wxterminal/wxt_gui.h:  wxWidgets versions > 2.8 want
	the main program to call XInitThreads(), but fail to specify -lX11 in
	wxt-config.   So we force this ourselves.   [=> reverted 2014-06-20]
	Bug #1401

	* src/graphics.c (xtick2d_callback): Clip r axis tics and tic labels to
	the bounding box of the plot.
	Bug #1290

2014-06-15  Dmitri A. Sergatskov  <dasergatskov@gmail.com>

	* configure.in: Add LRELEASE for Qt5 autoconfiguration

2014-06-15  Bastian Maerkisch  <bmaerkisch@web.de>

	* src/plot.c (main):  Fix persist mode on Windows when reading
	from a pipe.
	See Bug #1322

2014-06-15  Akira Kakuto  <kakuto@fuk.kindai.ac.jp>

	* src/binary.c src/datafile.h src/syscfg.h:  LFS support on Windows
	for MSVC and MinGW.
	See also Patch #675

2014-06-14  Ethan A Merritt  <merritt@u.washington.edu>

	* src/axis.h src/axis.c src/boundary.c src/plot2d.c (eval_plots):
	Unlike all other axes, log scaling was being applied to the color axis
	(cb) in do_plot() rather than in the caller eval_plots().
	This caused "refresh" (as opposed to "replot") to fail.  Move the
	log-scale correction up to eval_plots() like the other axes.
	Bug #1425

	* src/misc.c (prepare_call):  Allow parenthesized expressions as
	call parameters.  The value is passed as a string.

	* src/command.c (exit_command):  New option "exit error 'message'"
	prints the message and return to the top command line, breaking out
	of any loops or calls cleanly.  In non-interactive mode the program
	then exits.

2014-06-13  Bastian Maerkisch  <bmaerkisch@web.de>

	* src/qtterminal/qt_term.cpp (qt_waitforinput):  Fix index error
	when trying to stop thread which reads from pipe.
	Bug #1426

2014-06-13  Ethan A Merritt  <merritt@u.washington.edu>

	* src/datafile.c (df_generate_pseudodata):  Do not try to access plot
	structure if we were called from fit rather than plot.
	Bug #1427

2014-06-12  Christoph Bersch  <usenet@bersch.net>

	* term/lua.trm term/lua/gnuplot-tikz.lua:
	Scale dashlength with linewidth.

2014-06-11  Ethan A Merritt  <merritt@u.washington.edu>

	* src/mouse.c (event_reset) src/qtterminal/QtGnuplotWindow.{h|cpp}:
	Window close events from qt were not being passed through to the main
	program, so "pause mouse close" did not work. Also a backgrounded
	instance could hang rather than exit when the last plot window closed.
	Bug #1418

	* src/fit.c: Remove spurious test and error message for time data
	with only 2 columns in the using spec.
	Bug #1424

	* man/gnuplot.1: update

2014-06-11  Mojca Miklavec  <mojca.miklavec.lists@gmail.com>

	* term/aquaterm.trm:  Correctly support encoding CP1252.

2014-06-11  Tatsuro MATSUOKA <tmacchant3@yahoo.co.jp>

	* win/gnuplot.iss:  Include Qt platform DLLs in distribution package.

2014-06-10  Ethan A Merritt  <merritt@u.washington.edu>

	* docs/gnuplot.doc:  Add a section explaining the "persist" option.
	Bug #1418, #1419

	* term/post.trm term/svg.trm src/qtterminal/qt_term.cpp:
	Add an empirical scale factor to the dashlength*linewidth computation to
	make the resulting patterns closer in total size to the built-in ones.

2014-06-10  Christoph Bersch  <usenet@bersch.net>

	* term/post.trm term/svg.trm:  Scale dashlength with linewidth.

2014-06-09  Daniel J Sebald  <daniel.sebald@ieee.org>

	* src/qtterminal/QtGnuplotWidget.cpp (processEvent):  Always "resize"
	the initial plot to its own size.  This may work around strangeness on
	some systems that create the initial qt plot window with the wrong size.
	Bug #1417 (forwarded from Debian) Patch #661

2014-06-09  Bastian Maerkisch  <bmaerkisch@web.de>

	* src/win/wgdiplus.cpp src/win/wgraph.c src/win/wgnuplib.h
	term/win.trm:
	Version 5 dashtypes. Custom dashtypes supported by GDI+ driver.

	* src/wxterminal/wxt_gui.cpp:  Also "restore" the window state on
	"raise".
	Bug #1389

	* src/win/winmain.c (WinMain):  Change type from PASCAL to CALLBACK.

	* src/fit.c:  Test if covariance matrix is available before saving
	it to user variables.

2014-06-08  Shigeharu Takeno  <shige@iee.niit.ac.jp>

	* docs/gnuplot.doc win/README-Windows.txt win/README-ja.txt
	docs/gnuplot-ja.doc:  sync to docs version 1.891

2014-06-07  Mojca Miklavec  <mojca.miklavec.lists@gmail.com>

	* src/wxterminal/gp_cairo.c:  Scale dashlength with linewidth, similar
	to what qt does.

2014-06-04  Bastian Maerkisch  <bmaerkisch@web.de>

	* src/plot.c src/win/winmain.c|h term/caca.trm:  Only if a wxt, caca
	or windows terminal window is open, the -persist option is handled by
	keeping the main input loop running. This is unfortunate but maybe the
	best we can do since we are missing a process fork or detach mechanism.
	This avoids a zombie process when no plot windows are open in a
	session. For the qt terminal -persist works as on other platforms
	since it uses a secondary process.
	Bugs #1308, #1335, #1343

2014-06-03  Ethan A Merritt  <merritt@u.washington.edu>

	* src/graph3d.c src/show.c src/save.c docs/gnuplot.doc:
	The hidden3d code processes the lines making up the plot border using
	the same algorithm as it does for the plot elements.  This renders
	partially occluded borders correctly for actual surfaces but fails to
	recognize occlusion for, e.g., 3D histograms drawn with impulses.
	New keyword option "set border behind" draws the border lines before
	the plot elements even for hidden3d plots.

	* src/term_api.h src/wxterminal/gp_cairo.c src/wxterminal/wxt_gui.cpp:
	Change the implementation of greying out inactive keybox entries in wxt
	to use a textbox rather than the active area of the key entry.
	Bug #1416

	* src/hidden3d.c (draw_vertex):  Handle p_type == PT_CHARACTER.

2014-06-02  Bastian Maerkisch  <bmaerkisch@web.de>

	* src/win/wgraph.c src/win/wgdiplus.cpp:
	Grey out key entries when corresponding plot is toggled off.

	* src/win/wgraph.c (GraphUpdateWindowPosSize) src/win/wgnuplib.h
	term/win.trm (WIN_options):  Immediately apply changes to window
	position and size.
	Bug #1400

	* src/datafile.h:  Revert the Windows LFS changes for now as
	they seem to cause problems on some systems.

2014-06-01  Ethan A Merritt  <merritt@u.washington.edu>

	* src/axis.c src/gadgets.c src/misc.c src/set.c src/unset.c:
	Replace magic numbers with LAYER_{BEHIND|BACK|FRONT}.

	* src/graph3d.c: Remove obsolete (always true) conditional
	USE_GRID_LAYERS.  Minor clean up for the grid layer logic.

2014-06-01  Tatsuro MATSUOKA <tmacchant3@yahoo.co.jp>

	* win/gnuplot.iss:  Include gnuplot_qt.exe in installer.
	Patch #689

	* src/qtterminal/gnuplot_qt.cpp:  Search for Qt translation files
	in gnuplot's installation directory on Windows.
	Patch #687

2014-06-01  Ethan A Merritt  <merritt@u.washington.edu>

	* src/datafile.h:  Partial support for LFS on Windows. Currently
	mostly useful for 64 bit builds since integers on the the gnuplot
	command line are limited to 31bits otherwise.
	Patch #675

2014-06-01  Bastian Maerkisch  <bmaerkisch@web.de>

	* config/mingw/Makefile:  Target 'clean' and 'veryclean' include
	Qt files, see patch #688.

	* config/mingw/Makefile win/gnuplot.iss:  Include RELEASE_NOTES.
	Add "qt" as option as default terminal.

2014-05-30  Ethan A Merritt  <merritt@u.washington.edu>

	* term/post.trm term/cairo.trm:  The "header" keyword for epslatex
	and related terminals can introduce a string of arbitrary length.
	Therefore it is not safe to try to store it in the fixed length
	term_options character array.
	Bug #1413

	* term/gd.trm:  Limit the stored length of the font so that term_options
	cannot overflow.
	Bug #1413

	* Makefile.am RELEASE_NOTES:  Include Release Notes in the distribution
	package.

	* FAQ.PDF:  Update for version 5.

	* src/gplt_x11.c:
	Grey out key entries when corresponding plot is toggled off.

2014-05-29  Akira Kakuto  <kakuto@fuk.kindai.ac.jp>

	* term/caca.trm:  Modify nominal codepage to accommodate CJK Windows.

2014-05-29  Tatsuro MATSUOKA <tmacchant3@yahoo.co.jp>

	* config/mingw/Makefile:  Support compilation of the qt terminal.
	Patch #684

2014-05-29  Karl Ratzsch  <ratzsch@uni-freiburg.de>

	* docs/gnuplot.doc:  Improve documentation of `update` command.
	Patch #686

	* src/win/wgdiplus.c src/win/wgraph.c:  Change order of pointtypes to
	match the sequence in other terminals (cairo, postscript, gd, svg).
	Patch #681

2014-05-28  Ethan A Merritt  <merritt@u.washington.edu>

	* src/graph3d.c (plot3d_points):  Handle pointtype PT_CHARACTER.

	* src/plot3d.c:  Rearrange the order of testing for plot style options
	so that it is not possible to end up with uninitialized font or text
	properties.

2014-05-27  Ethan A Merritt  <merritt@u.washington.edu>

	* src/datafile.c (df_readascii): Report status DF_UNDEFINED if a data
	value evaluates to the constant "NaN", just as if we calculated it on
	the fly to be e.g. 1/0.
	* src/stats.c: Remove out-of-date comment that incorrectly describes
	what happens in this case.
	Bug #1408

2014-05-26  Ethan A Merritt  <merritt@u.washington.edu>

	* term/js/gnuplot_svg.js term/svg.trm:
	Grey out key entries when corresponding plot is toggled off.

	* src/qtterminal/QtGnuplotItems.* src/qtterminal/QtGnuplotScene.cpp:
	Grey out key entries when corresponding plot is toggled off.

	* src/wxterminal/wxt_gui.cpp (wxt_grey_out_key_box):
	Grey out key entries when corresponding plot is toggled off.

2014-05-24  Bastian Maerkisch  <bmaerkisch@web.de>

	* src/wxterminal/wxt_gui.cpp (wxt_waitforinput):  Do not wait for an
	event when only checking for mouse events.
	Bugfix

2014-05-23  Ethan A Merritt  <merritt@u.washington.edu>

	* src/boundary.c:  A width adjustment for the length of the key title
	was being applied to every column of entries in the key instead of just
	once for the whole key.  Apply the "set key {no}enhanced" property to
	the key title as well as to the individual plot titles.
	Bugfix.

2014-05-19  Ethan A Merritt  <merritt@u.washington.edu>

	* src/wxterminal/wxt_gui.h: Apparently wxWidgets3 (wxgtk3) threads call
	into Xlib but fail to initialize X threading before doing so. Therefore
	we must call XInitThreads before forking wxt threads.
	Bug #1401

2014-05-19  Karl Ratzsch  <ratzsch@uni-freiburg.de>

	* term/emf.trm: Add point types pentagon (14) and filled pentagon (15)

2014-05-16  Ethan A Merritt  <merritt@u.washington.edu>

	* src/term.c (load_linetype):  As documented, "set linetype cycle N"
	should only affect line properties (color, width, dash), not point
	properties (type, interval, size).  This got lost somewhere, which
	meant point types > linetype_recycle_count were never used by default.
	Now they are.  This means that, as intended, 'with linespoints' cycles
	through (linetype_recycle_count * terminal's_max_point_type) distinct
	combinations before repeating so long as those two numbers are
	mutually prime.  Unfortunately that's not guaranteed and is terminal-
	dependent.  We really need a "set pointtype cycle M" command also so
	that you can choose M to be prime relative to N.
	Bugfix.

	* INSTALL docs/gnuplot.doc:  Update description of new features.

2014-05-15  Ethan A Merritt  <merritt@u.washington.edu>

	* configure.in PATCHLEVEL src/version.c docs/titlepag.tex:
	Bump version information to 5.0.rc1

	* demo/dashtypes.dem:  Avoid irrelevant warning message.

2014-05-14  Karl Ratzsch  <ratzsch@uni-freiburg.de>

	* term/svg.trm src/wxterminal/gp_cairo.c:
	Add point types pentagon (14) and filled pentagon (15)

	* src/qtterminal/QtGnuplotItems.cpp:
	(EAM) Add point types pentagon (14) and filled pentagon (15)

2014-05-13  Ethan A Merritt  <merritt@u.washington.edu>

	* src/command.c src/tables.c src/tables.h: Remove undocumented routine
	test_time(). It was never updated to handle sub-second time precision,
	and in any case the functionality is now covered adequately by
	"print strptime()" and "print strftime()".

	* src/color.c (filled_polygon_3dcoords filled_polygon_zfixed)
	src/pm3d.c (filled_color_contour_plot):	 The option "set pm3d at C" is
	undocumented and doesn't work anyhow.  Wrap the corresponding code in
	#ifdef PM3D_CONTOURS . This disabled code may or may not be useful for
	some future implementation of filled contours.

	* term/post.trm (PS_dashtype): Always stroke the previous path before
	setting a new dashtype.

2014-05-11  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/util.c (LOCAL_BUFFER_SIZE): New constant.
	(gprintf): Use constant to identify buffer size, instead of typing
	the same magic number multiple times. Insert warning about
	remaining magic number.

	* src/plot2d.c (get_data): Fix buffer overflow a bit more cleanly.
	(compare_boxplot_factors): Insert warning about magic number.

2014-05-11  Ethan A Merritt  <merritt@u.washington.edu>

	* src/plot2d.c (get_data): fix buffer overflow

	* src/datafile.c (f_stringcolumn): Return an empty string if asked for
	stringcolumn(N) on an empty field of a *.csv file.  Otherwise it would
	return NULL which may cause a segfault later on.
	Bugfix.

	* src/datafile.c (df_readascii): If xticlabels(f(n)) returns a
	non-string value then do not generate an axis tic.  It used to issue
	a warning about illegal string values but generated a tic anyway.

2014-05-10  Dima Kogan  <dima@secretsauce.net>

	* src/mouse.c (do_zoom rescale_around_mouse):  Handle various conditions
	that caused zooming around the current mouse position to fail.
	Re-applied after tracking down conflict.

	* docs/gnuplot.doc: various small corrections
	* docs/gnuplot-ja.doc term-ja.diff:  Sync translation to version 1.887

2014-05-10  Ethan A Merritt  <merritt@u.washington.edu>

	* term/gd.trm: Do not allow setting terminal size to 0.  Bug #1398

2014-05-10  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* term/lua.trm: Ensure initialization of alpha.

	* src/hidden3d.c (store_polygon): Ensure initialization of v[],
	just in case somebody calls this function with an illegal
	'direction' enum value.

	* src/win/wgraph.c (PATTERN_BITMAP_LENGTH): Give name to magic number.
	(pattern_bitmaps): Use new name.

	* term/emf.trm (PATTERN_BITMAP_LENGTH): Give name to magic number.
	(pattern_bitmaps): Use new name and make const.
	(EMF_filled_polygon): Define pattern pointer more locally and make
	it point to const. Use named constant in loop.  Fix table
	underrun.

	* src/win/wgnuplib.c (GetInt): Add some parentheses.

	* src/stats.c (statsrequest): Initialize local data structs, to
	avoid warnings about printing uninitialized results.

	* src/readline.c (BACKSPACE): Define as a character constant, not
	some hex number.
	(readline): Write TAB as character constant, not some hex number.

	* src/interpol.c (gen_interp_frequency): Ensure initialization of
	y_total regardless of smooth type.

	* src/plot3d.c (grid_nongrid_data): Ensure initialization of
	numpoints.

	* src/pm3d.c (pm3d_plot): Ensure initialiation of gray.

	All the following concern the same problem: Macros from <ctype.h>
	cannot safely be called with arguments of type 'char' (because
	that may be signed).  Such values have to be cast to unsigned char
	on passing.

	* src/win/wtext.c (TextPutStr): See above.

2014-05-08  Dima Kogan  <dima@secretsauce.net>

	REVERT patch from 2014-04-26 because it broke normal zoom operations.
	* src/mouse.c (do_zoom rescale_around_mouse):  Handle various conditions
	that caused zooming around the current mouse position to fail.

2014-05-08  Ethan A Merritt  <merritt@u.washington.edu>

	* src/axis.h (ACTUAL_STORE_WITH_LOG_AND_UPDATE_RANGE)
	src/plot2d.c (store2d_point) src/plot3d.c (get_3ddata)
	src/datafile.c (df_readascii) src/tabulate.c:
	Revised handling of NaN or Inf in the input data stream.  The program
	used to set type=undefined for this point but left all the data fields
	untouched (i.e. left them containing random garbage).  Version 5 fills
	in all data fields, including the one[s] containing NaN or Inf.
	This means that the output from "set table" matches the input data
	whereas before any line marked "u" contained garbage in the data fields.

	Note: For 3D data z=NaN or z=Inf is replaced by z=0.  This is needed to
	avoid problems with image data.  Possibly this special case should be
	handled in the image code itself rather than at the input stage.

	* src/plot2d.c (impulse_range_fiddling) src/plot3d.c: Don't extend
	range to zero for log-scaled axes.

2014-05-06  Ethan A Merritt  <merritt@u.washington.edu>

	* term/emf.trm: Custom dashtype support.

	* configure.in term/pdf.trm: Modify PDFlib terminal for use with
	version 5 dashtypes (but no custom dashtype support).  Do not build
	by default.

2014-05-05  Ethan A Merritt  <merritt@u.washington.edu>

	* src/gp_types.h src/graphics.c (place_objects do_rectangle)
	src/misc.c (lp_parse) src/save.c (save_object) src/set.c (set_obj):
	Allow object borders to have a full set of line properties including
	dashtype.

	* docs/gnuplot.doc: Update documentation to better describe recent
	changes.

	* src/qtterminal/QtGnuplotScene.cpp: Always use a solid line to draw
	point symbols, even if the current linetype has a dash pattern.

	* term/cairo.trm term/canvas.trm term/post.trm term/svg.trm term/wxt.trm
	term/x11.trm src/term.c:  Terminals that have been upgraded to version 5
	dash handling should ignore the "dashed/solid" terminal setting.

	* src/plot2d.c (impulse_range_fiddling) src/plot3d.c:  Autoscaled plots
	"with impulses" should include y=0 (z=0 in 3D) unless log-scaled.

2014-05-05  Tatsuro MATSUOKA <tmacchant3@yahoo.co.jp>

	* src/qtterminal/po/qtgnuplot_ja.ts: Update translations

2014-05-03  Ethan A Merritt  <merritt@u.washington.edu>

	* src/qtterminal/po/qtgnuplot_ja.ts: Update translations.

2014-05-01  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* config/mingw/Makefile (LDFLAGS2): Add auto-import flag.
	($(TARGET)): Add icon files and Makefile as dependencies.

	* config/config.mgw, config/config.cyg: The set of used /
	available configuration macros has changed across the past several
	years.

	* src/stdfn.h (sgn): Fix parenthesization of macro.
	(PATH_MAX): CLang compiler on Cygwin needs a silly little tweak.

	* src/graphics.c (samesign): Improve parenthesization a bit.

2014-05-01  Ethan A Merritt  <merritt@u.washington.edu>

	* demo/gantt.dem demo/html/*:  Add Gantt chart to demo collection.
	Add dashtypes to demo collection.

	* src/show.c:  Show "fixed" property of arrow style.

2014-04-29  Ethan A Merritt  <merritt@u.washington.edu>

	* src/datafile.c (f_timecolumn): Replace the old 1-parameter function
	timecolumn(col) with a 2-parameter timecolumn(col,"timeformat"). The
	old version had no way to handle time data that didn't correspond to
	a coordinate on a plot axis in time format (e.g. set xdata time).
	It would segfault if the function appeared in a using spec slot >= 2.
	Now we require an explicit format, so data input is dissociated from
	any particular axis or time setting.
	Bug #1394

	* src/gplt_x11.c term/x11.trm term/xlib.trm:
	Custom dashtype support for X11.

2014-04-28  Dima Kogan  <dima@secretsauce.net>

	* src/mouse.c src/mouse.h src/set.c src/show.c docs/gnuplot.doc:
	Remove the distinction between "coordinate format echoed to the screen
	during mousing" and "coordinate format saved to the clipboard on click".
	This removes the default bindings for hotkeys 3 and 4.

2014-04-28  Shigeharu Takeno  <shige@iee.niit.ac.jp>

	* docs/gnuplot-ja.doc term-ja.diff:  Sync translation to version 1.882

2014-04-28  Ethan A Merritt  <merritt@u.washington.edu>

	* src/graphics.c src/graph3d.c src/save.c src/show.c: Use named
	values LAYER_{BEHIND|BACK|FRONT} rather than magic numbers.

	* docs/gnuplot.doc: Add a section documenting the use of layers.

2014-04-27  Dima Kogan  <dima@secretsauce.net>

	* src/gplt_x11.c: Fix off-by-one error in selection string.
	Allow clipboard contents to be retrieved more than once.

2014-04-27  Ethan A Merritt  <merritt@u.washington.edu>

	* src/graphics.c (plot_steps): Avoid overflow in clipping code.
	==> Reverted in favor of fixing the clipping code itself.

	* src/gadgets.c (clip_line): It is not safe to use (A*B >= 0) as a
	substitute for the test (sign(A) != sign(B)).
	It fails when A and B are integers and their product overflows.
	Bugs #1390, #1392	See also Bug #1358

	* src/stdfn.h: Define a sgn() function.

	* src/graphics.c: Use sgn() function to define samesign().

	* src/mouse.c: No longer need a local definition of sgn().

2014-04-26  Dima Kogan  <dima@secretsauce.net>

	* src/mouse.c (do_zoom rescale_around_mouse):  Handle various conditions
	that caused zooming around the current mouse position to fail.
	Bug #1380
	[REVERTED 2013-05-08 because it broke normal zoom]

2014-04-25  Ethan A Merritt  <merritt@u.washington.edu>

	* src/misc.c (lp_parse):  Disallow defining "set lt N lt M".
	This used to mean "define effective linetype N to be the hidden device
	specific linetype M", except that in other contexts it meant "use
	effective linetype M rather than effective linetype N". Version 5
	distinguishes between color and dashpatten, so require an explicit
	command to set one or both rather than an ambiguous old-style request.

	* src/save.c (save_pm3dcolor save_linetype):  Save special linetypes
	by keyword rather than a magic number (e.g. lt bgnd rather than -3).

2014-04-24  Ethan A Merritt  <merritt@u.washington.edu>

	* src/gp_types.h src/misc.c (lp_parse) src/misc.h src/plot2d.c
	src/plot3d.c src/set.c:  Revise the parameters passed to lp_parse() so
	that the legal options can vary depending on the identity of the caller.

	* src/term.c (test_term): Reset to default font after Bold/Italic test.
	Bug #1387

2014-04-24  Dima Kogan  <dima@secretsauce.net>

	* src/mouse.c (do_zoom_scroll_up):  Fix typo that causes incorrect
	manipulation of y2 axis scale during zoom.
	Bug (Patch #647)

2014-04-23  Ethan A Merritt  <merritt@u.washington.edu>

	* src/command.c src/graph3d.* src/set.c src/show.c src/save.c
	docs/gnuplot.doc:  Introduce a scale parameter "set view map {scale}"
	and set the default size of a plot in this mode to approximately the
	same as a default 2D plot.

	* src/command.c (replotrequest):  It's now OK to have a range in a
	replot command, since it can be applied to the new plot piece only.

	* src/datafile.c (df_readascii):  If a read request returns a string
	rather than a numerical value, nevertheless fill in the numerical
	value as NaN.  This is better than leaving some random garbage there
	(in practice probably some earlier data value).
	Bugfix.

2014-04-21  Ethan A Merritt  <merritt@u.washington.edu>

	* term/canvas.trm: Support for custom dashtypes.

2014-04-20  Jérôme Lodewyck  <lodewyck@users.sourceforge.net>

	* src/qtterminal/po/*.ts: Update translations.

	* src/qtterminal/qt_conversion.cpp: Add new encoding types.

	src/qtterminal/qt_term.cpp src/wxterminal/wxt_gui.cpp
	src/wxterminal/wxt_term.h term/qt.trm term/wxt.trm: new terminal option
	"position" that specifies the initial position of the plot window.
	Applies to Qt and wxt terminals. Feature request #386.

2014-04-19  Ethan A Merritt  <merritt@u.washington.edu>

	* src/command.c (test_command):  When "test" is issued before any plot
	command, suppress error messages if the window is resized.

	* term/PostScript/prologue.ps term/PostScript/prologues.h:
	Update PostScript prolog for version 5 and regenerate headers.

	* term/post.trm:
	Support for custom dashtypes in PostScript output.

2014-04-18  Ethan A Merritt  <merritt@u.washington.edu>

	* term/svg.trm (set_dashtype):  Fix potential buffer overrun;

	* src/misc.c (parse_dashtype):  A custom pattern must contain an even
	number of entries.

	* demo/dashtypes.dem demo/all.dem:  New dashtype demo.

	* src/qtterminal/QtGnuplotEvent.h src/qtterminal/QtGnuplotScene.cpp
	src/qtterminal/qt_term.cpp src/qtterminal/qt_term.h term/qt.trm:
	Support for custom dashtypes and dashlength in qt terminal.
	Change implementation of "lt nodraw" from background color to NoPen.

	* src/term.c (enhanced_recursion):  Consume only a single space following
	the font name in an enhanced text string "{/Fontname      text}".

	* docs/gnuplot.doc:  Initial documentation for `set dashtype` and
	dash properties in version 5.

2014-04-17  Ethan A Merritt  <merritt@u.washington.edu>

	* src/misc.c (parse_dashtype) src/save.c (save_dashtype) src/term_api.h
	src/term.c (term_apply_lp_properties) demo/dashcolor.dem:
	Fix some glitches found while testing custom dashtypes.

	* src/term.c (test_term): Exercise bold/italic.  Longer line samples to
	make it easier to distinguish dashtypes.  Minor layout changes.

	* term/svg.trm:  Support for custom dashtypes.

	* src/wxterminal/gp_cairo.* src/wxterminal/wxt_gui.*
	src/wxterminal/wxt_term.h term/cairo.trm term/wxt.trm:
	Support for custom dashtype in all cairo-based terminals.

2014-04-14  Dima Kogan  <dima@secretsauce.net>

	* src/mouse.c (event_buttonpress):  Flip direction of horizontal
	scrolling to match the convention used by vertical scrolling.

2014-04-14  Ethan A Merritt  <merritt@u.washington.edu>

	* configure.in (AC_FUNC_FSEEKO) src/datafile.h: LFS support part 2.
	If possible, use fseeko/ftello to navigate input data files.

2014-04-13  Ethan A Merritt  <merritt@u.washington.edu>

	* configure.in (AC_CHECK_TYPES([off_t])) src/syscfg.h (#define off_t)
	src/binary.c src/datafile.c src/datafile.h:  Change the declared type
	of all variables contributing to calculation of file offsets from (int)
	to (off_t).  This is sufficient to allow seeking in files > 2GB on 64bit
	platforms.  It may also allow LFS support on some 32bit platforms if
	compiled with -D_FILE_OFFSET_BITS=64 but in general it will also be
	necessary to replace fseek/ftell with fseeko/ftello (32bit linux) or
	_fseeki64/_ftelli64 (MSVC).

2014-04-11  Ethan A Merritt  <merritt@u.washington.edu>

	* src/datafile.c (df_binary_details[]): Handle int64 and uint64 types
	even if current platform has sizeof(long) = 4.
	Bugfix

2014-04-08  Ethan A Merritt  <merritt@u.washington.edu>

	* src/save.c (save_linetype) src/misc.c (lp_parse)
	src/graphics.c (plot_lines) src/graph3d.c (do_3dplot plot3d_lines)
	src/boundary.c (do_key_sample):

	New linetype keyword "nodraw" maps to existing internal value LT_NODRAW.
	Apply this in the graphics layer rather than the terminal layer in order
	to distinguish between line properties and point properties.
	I.e. this draws blue points but no lines:
	  plot $FOO with linespoints lt nodraw pointtype 6 lc rgb "blue"

	* src/term.c (term_apply_lp_properties):  Distinguish between l_type
	values that really indicate a linetype (e.g. LT_NODRAW, LT_AXIS) and
	those which indicate a dash pattern. Send the former directly to
	term->linetype(). Send the latter to term->dashtype(), which may itself
	call term->linetype() if there is no private implementation of dashes.

2014-04-07  Ethan A Merritt  <merritt@u.washington.edu>

	* src/term.c (null_dashtype):  Ignore custom dashtypes. Pass through
	dashtypes > 0 to term->linetype(). Treat negative dashtypes as LT_BLACK.
	This should allow terminals without a private dashtype implementation to
	continue working as they did before (pre-version 5).

	* src/plot2d.c (eval_plots):  Don't call lp_parse if all we want is
	a fill color.

	* src/boundary.c (do_key_sample) src/graphics.c (plot_boxes plot_c_bars):
	Funnel requests for linetype changes through term_apply_lp_properties().

	* demo/all.dem:  Add varcolor.dem to the test set.

2014-04-06  Christoph Bersch  <usenet@bersch.net>

	* src/graphics.c (fill_between):  It is no longer necessary to clip in
	this routine because the component quadrilaterals will be clipped later.

2014-04-05  Ethan A Merritt  <merritt@u.washington.edu>

	* src/set.c (set_table): Name leak.

2014-04-05  Bastian Maerkisch  <bmaerkisch@web.de>

	src/datablock.h src/gadgets.c src/gadgets.h src/plot2d.c src/set.c
	src/tabulate.c src/tabulate.h src/unset.c src/util.c src/util.h:
	'set table $datablock' redirects table output to a named data block.
	Patch #662

2014-04-04  Ethan A Merritt  <merritt@u.washington.edu>

	* src/term.c (load_linetype):  If a line style is based on a lt < 0
	(LT_NODRAW, LT_BACKGROUND, LT_BLACK, etc), take only the line color.
	FIXME: LT_AXIS should also take the dash pattern but that mechanism
	isn't fully in place yet.
	Bug #1369

	* src/util.c (value_to_str):  Fix error in buffer length accounting.
	Bug #1372

	* src/alloc.c src/alloc.h src/bf_test.c: The conditional code in
	alloc.c for tracking memory allocation/free has bit-rotted to a point
	where the program segfaults on entry if it is enabled.  Since this sort
	of accounting is now better done using valgrind it is not worth fixing
	the old code.  Delete it.

	* src/alloc.c: Although freeing old help messages may free some memory,
	entangling the help system with every memory allocation seems excessive.
	If we're about to run out of memory there are deeper problems than old
	help messages.

	* configure.in: Remove EXPERIMENTAL warning from older options.

	* src/save.c src/set.c src/term.c:  Code style / whitespace cleanup

	* src/set.c (set_dashtype) src/misc.c (parse_dashtype):  Add comments.
	Truncate dashtype string to match size of stored pattern array.

2014-04-03  Bastian Maerkisch  <bmaerkisch@web.de>

	* src/fit.h (error_ex):  Add noreturn attribute to avoid compiler
	warnings.

	* src/fit.c:  Correct test for invalid covariance matrix.

	* src/util.h (int_error, os_error, graph_error):  noreturn attribute
	for MSVC.

	* src/wgdiplus.cpp (drawgraph_gdiplus) src/win/wgraph.c (drawgraph):
	Test if command list is available.

	* src/win.trm (WIN_update_options) src/win/wmenu.c:  Incomplete format
	strings.

2014-04-02  Ethan A Merritt  <merritt@u.washington.edu>

	* src/misc.c demo/heatmaps.dem docs/gnuplot.doc:
	Document and add a demo for "with image pixels" (formerly "failsafe").

	src/show.c src/tables.c src/tables.h src/term.c src/unset.c:
	Revise "set pm3d hidden3d <lt>" to match other places where you can
	specify line properties.
	- Full syntax is now "set hidden3d {no}border {line-properties}"
	- Individual line properties can be overridden in the plot command
	- Old sytax is accepted as a synonym for "set hidden3d border lc <lt>"

	* demo/transparent_solids.dem docs/gnuplot.doc:
	Update documentation and demo to show new syntax

	* src/contour.c (end_crnt_cntr): Initialize blank label in new contour.

2014-04-01  Ethan A Merritt  <merritt@u.washington.edu>

	* src/command.c (test_palette_command):  Write the palette colors into
	a datablock $PALETTE rather than writing them as in-line data in a temp
	file.  Simplify the internal command sequence that generates the test
	output.  TODO: Move the command sequence into a datablock as well.

2014-03-30  Bastian Maerkisch  <bmaerkisch@web.de>

	* term/caca.trm:  Change codepage from 932 to 437 on Japanese Windows.
	Apparently this fixes display problems, although libcaca uses unicode
	functions to write to screen.
	Bug #1361

	* src/eval.c src/internal.c|h src/parse.c:  Implement f_words instead
	of treating it as a special case in the parser.

	* src/command.c src/command.h src/plot.c src/stdfn.h src/syscfg.h
	src/win/wgraph.c src/win/winmain.c src/win/wprinter.c:  Include file

2014-03-29  Ethan A Merritt  <merritt@u.washington.edu>

	* src/term.c (multiplot_current_panel) term/svg.trm src/term_api.h:

2014-03-24  Ethan A Merritt  <merritt@u.washington.edu>

	* src/graphics.c (place_objects do_rectangle): When fillcolor for an
	objects is given as a linecolor it should be interpreted as referring

	* src/command.c: clean up to remove compiler warnings.

	* term/emf.trm:  Bold/Italic markup in enhanced text mode

	src/set.c src/show.c src/unset.c docs/gnuplot.doc demo/ellipse.dem
	demo/fitmulti.dem demo/gen-random.inc demo/rugplot.dem:
	Implement 'set print $datablock' which redirects 'print' output to
	an in-memory datablock.
	Patch #662

	* src/setshow.h src/show.c src/util.c src/util.h:  Factor out new
	routine value_to_str() which returns a string representation of a
	struct value from disp_value().

	* demo/tango_colors.dem:  set linetype cycle.

	* docs/plotstyles.gnu:  Encoding is utf8.

	* src/win/wcommon.h src/win/wgraph.c:  Fix const-ness for
	enhanced_recursion().

	* src/util.c (gprintf):  Skip leading zeroes of negative exponents.

2014-03-22  Ethan A Merritt  <merritt@u.washington.edu>

	* docs/gnuplot.doc docs/doc2tex.c docs/titlepag.tex:
	Update documentation New Features, Changes for version 5.

	* src/plot.c (init_session) src/set.c (set_colorsequence) src/setshow.h
	src/show.c src/tables.c src/tables.h src/term_api.h:
	New command:
		set colorsequence {default | classic | podo}
	Built-in command to select one of the linetype color sequences provided
	in .../share.  The default sequence is visibly changed from the old
	red/green/blue ugliness, which should make users immediately aware that
	the colors can be customized.

	* src/set.c (set_linestyle):  Dash type of newly created linetype should
	by solid unless otherwise specified.

	* src/misc.c:  Allow `black` as a colorspec or linetype, analogous to
	`bgnd`.

2014-03-21  Ethan A Merritt  <merritt@u.washington.edu>

	* src/parse.c (check_for_iteration next_iteration):
	Replace overly clever checks for end condition already satisfied with
	one that doesn't fail due to overflow of integer multiplication.
	Bug #1358

	* src/term.c (enhanced_recursion) term/post.trm(ENHPS_OPEN):
	The bold/italic support code has revealed a problem with PostScript
	output. The core code assumes that passing a blank font name means
	"keep the previous font" or at worst "use the default font". post.trm
	failed to do this for some command sequences. Fix it in two places.
	In term.c pass the previous font if we already know it.
	In post.trm fall back to the default rather than place a blank
	string in the ouput *.ps file.
	Bug #1359

2014-03-20  Bastian Maerkisch  <bmaerkisch@web.de>

	* src/set.c src/term.c src/term_api.h src/util.c src/win/wgraph.c
	src/wxterminal/gp_cairo.c term/aquaterm.trm term/pdf.trm term/post.trm
	term/pslatex.trm term/svg.trm:  Add support for codepage 1252, the
	standard Western European encoding on Windows.

	* src/set.c:  "set encoding locale" only handles utf8 and sjis. Extend
	this to all supported encodings on Windows, probably the only platform
	where this is still relevant.
	Bug #1270

	* demo/dashcolor.dem:  UTF-8 encoding.

	* src/fit.c (show_results):  Do not try to print parameter errors if
	the covariance matrix is unavailable or invalid.

2014-03-20  Thomas Henlich  <thenlich@users.sourceforge.net>

	* term/PostScript/cp1252.ps:  CP1252 encoding support for PostScript
	terminal. Based on Patch #341, but with non-standard characters
	removed.

2014-03-20  Ethan A Merritt  <merritt@u.washington.edu>

	* term/svg.trm:  svg was losing the current linetype (i.e. dash type)
	between drawing the key sample and drawing the main plot.

2014-03-19  Bastian Maerkisch  <bmaerkisch@web.de>

	* src/stdfn.c src/stdfn.h src/internal.c src/win/winmain.c
	src/win/wtext.h config/config.nt:  Standard compliant replacements
	of snprintf() and vsnprintf() for MSVC.  Note that _snprintf does set
	errno=ERANGE if the destination buffer is too small.

2014-03-19  Ethan A Merritt  <merritt@u.washington.edu>

	* src/plot2d.c: Fix parsing error for "with lp pt 'X', ..."

	* src/boundary.c src/boundary.h src/graphics.c:  Refactor code that
	draws key samples for point plots.

	* configure.in term/gpic.trm src/term.h:
	Add configuration option --with-gpic

	* configure.in src/term.h:  FrameMaker now allows import of svg, so the
	utility of the ancient mif v3 support is dubious. Disable by default.
	Add configuration option --with-mif

	* demo/lines_arrows.dem demo/stringvar.dem demo/html/Makefile
	demo/html/index.* demo/html/webify.pl: Update demos for version 5.

2014-03-19  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/misc.c (parse_dashtype): Avoid warning about assignment used
	as a condition value.  Some reindentation.

2014-03-19  Jérôme Lodewyck  <lodewyck@users.sourceforge.net>

	* src/qtterminal/QtGnuplotScene.cpp
	src/qtterminal/QtGnuplotItems.h src/qtterminal/qt_term.cpp:
	Implement image clipping for the Qt terminal.  Fix issue with
	unsigned variables in terminal coordinates.  Bug #1349

2014-03-18  Peter Juhasz  <juhaszp@users.sourceforge.net>

	* src/term.c src/set.c: Fix leaks and invalid reads associated
	with dashtype strings.

2014-03-18  Ethan A Merritt  <merritt@u.washington.edu>

	* src/wxterminal/gp_cairo.c:  PANGO_WEIGHT_NORMAL is not the same as 0.

	* term/x11.trm:  Make the "persist" flag local to x11 and remember
	what is was the last time we set the terminal to x11.
	Bug #1348

2014-03-18  Jérôme Lodewyck  <lodewyck@users.sourceforge.net>

	* src/qtterminal/QtGnuplotEvent.* src/qtterminal/QtGnuplotWindow.cpp
	src/qtterminal/QtGnuplotWidget.cpp src/qtterminal/QtGnuplotScene.cpp:
	Block events that come from inactive plot widgets.

2014-03-17  Peter Juhasz  <juhaszp@users.sourceforge.net>

	* src/term_api.h src/misc.c src/misc.h src/save.c src/save.h:
	Parse and save dashtype specification in the form of "-_. " or
	"(1.0, 0.3, 1.5, 2.0)". In the latter form alternating numbers
	specify dash lengths and spaces between them.

	* src/gadgets.c src/gadgets.h:
	Added new type custom_dashtype_def and global variable
	first_custom_dashtype in preparation of new "set dashtype" command.

	* src/gadgets.h src/misc.c src/set.c src/setshow.h src/show.c
	src/tables.c src/tables.h src/term_api.h src/unset.c:
	New commands 'set|show|unset dashtype <N> <dashtype_spec>' to
	specify permanent, user-defined dashtypes.

	* src/termp_api.h src/term.c src/misc.c: lp_parse() loads dashtype
	from the list of user-defined dashtypes if the absence of an explicit
	definition.

2014-03-16  Ethan A Merritt  <merritt@u.washington.edu>

	* src/axis.c src/axis.h src/gadgets.c src/gadgets.h src/graphics.c
	src/misc.c src/plot2d.c src/set.c src/term_api.h docs/gnuplot.doc
	docs/plotstyles.gnu:
	New point type that consists of a single character (possibly a
	multibyte character).  This is particularly useful as
	    plot $FOO with linespoints pointtype "#" pointinterval -1
	where # is the desired character drawn at each point.

2014-03-16  Peter Juhasz  <juhaszp@users.sourceforge.net>

	* src/term_api.h src/term.c src/misc.c src/plot2d.c src/plot2d.c
	src/set.c src/save.c src/graphics.c src/gadgets.c src/gadgets.h:
	Introduce new "dashtype" line property that controls dot/dash
	pattern independently. Allow it in "set|show linetype|linestyle",
	"plot", etc., display it in "save".
	Only numeric "dashtype N" supported for now.
	New function dashtype() added to termentry struct, but none of the
	terminals use it yet.

	* src/set.c (set_linestyle): Set pm3d_color.type to TC_LT and
	pm3d_color.lt to line number by default. This is necessary because
	since the use_palette flag was removed, pm3d_color information is
	used everywhere, yet, it was not set properly. This resulted,
	among others, a broken "show linetype" output with empty "linecolor"
	spec.

2014-03-16  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/axis.h (en_minitics_status): Give enum a typedef name, too.
	(axis): Use new type for element of AXIS struct, instead of int.

	* src/axis.c (gen_tics): Simplify by using local OO-like "this"
	pointer variable.  Remove pointless local variable "minifreq".
	Treat "minitics" variable as a proper enum everywhere (no
	set/compare to zero).
